To all 'whom t may comme Be it known. that l, l/Viiemmi F.

The pin 1&2 is 'rilevabile in the end. oit the iiell.erank lever 1113 the loloclr. 111 travels in a circular 15 parte wlxen the main slialit 50 is revolved.

By this combination ll am enabled to change the location oi tile end 147 ol the pin 141-5 by loosening thesetsorew 1413 and turning; tlie pin in the bell-crank lever and then resetting the setserew.

'llie eecentrie end 1417 of the pin 145 lies within a yoke 148 'formed in the lower end lo ol the told-presser 531. The resultof this construction is that tlie nell-crank lever 14:3

is o-soillated .troni the main shaft and tllereby' imparts an 'up and down movement of that parl; ot tlie told-presser carrying tlie :told-pressingn member 130, in order to eriforin tlie pressing; operation. betere stated, lille pin 117 may be adjusted Within oertain limits and thereby the up and down path of the told-pressing member is deter- -lo mined in order to prevent that member strikingf the work support when being operated. .llt time saine time this construction permits oil a very line'adjustinent in tliis respeot.

lft `will las noted that 'the fold-pressing member 130 is so formed that it has a out away portion. sliownin 2 and .8 at 150. Cutting away' the portion of the foldpressinp; member 1&3@ at 150 results in torm- Eil ing a reduced portion. 152 on the fold-pressing; member. The latter so arranged in the machine that the reduced portion 152 lies,

For the purpose of slitting the edge oli tlie material being folded Whenever desired at the will of the operator and without interfering with the operation of the machine7 li provide a movable upper cutting knife 24: 75 cooperating witli a lower knife-block 23.

rllie upper knieQll is fastened bya screw 156 to the upper eud "of a bell-crank lever 15'? mounted loosely on the bearing shaft The lower end of said lever 157 is 8o slotted to receive the pin 145. The knie is vibrated from the main shaft through-the medium of the bell-crank lever 143, pin 115, and bell-crank lever 157.

'111e lower knife-block 23 is adjustalaly 85 mounted on a slide bleek 160 by means olf a screw 161 passing through a slot in the linil'elolock. rllhe slide block is supported in the yoke 11 and is positively held in suoli position that the knife-block 23 is in opera- 9G tive relation with the "upper knife for slit:a tingAr purposes. The means for holding the slide-block in operative position. consists of a'cain 163 in tlieform ot' a segment oi' a circle pivotally mounted at 1.64: on the yoke l1. o5 The cam is provided with 'a flange the edge of which serves as the cam-surface 165 ad- I justed to engage a depending pin 167 Set in` the'end of the slide-block 160.

A spring 169 is provided for keeping the 100 pin 167 in positive engagement at all times with the earn face 165.v 1n order to suspend the cutting operation without interrupting A the operation of, the machine and at the will of the operator, I provdetreadle operated 105 means for liloving the slide-.block 160 toward the operator and thereby the lower cutting knife-block 23 out of cutting 'engagement with the upper movable knife 2l.

These means consist of a lever 170 secured 11o tothe cam 163 and a treadle rod 172 which may 'be attached to a treadle not shown'. When the treadlte is depressed the arm 1'l'0- is drawn downwardly' turning the' cam 163 and presenting the camsurlaee 165 to the 115 pin 167 andthe spring 169 then'draws the slide-block 160 to the right, referring to lig. 8, and moves the imite-block 23 out of operativo engagement Witlithe upper knife 2st. When the pressure on the treadle is re- 12o leased a spring returns the cam 163 to itsnorma-l position and the knife is then again in cutting engagement with the lower block 23. I

1t will kloe noticed thatan important :tear 125 ture of this invention is the provision of novel means for raising' the folding instru mentalities which are mounted on the upper feeding upoi'zirinns, both of said ymvans being minimi by said nvexhnnging arm, a liftsbax'tt for imparting za reciprocating movenii-nt m mid fwdinf und said holding means und ti'wuliv operating means forrrocking f-:iiii Iit'tlhimfr 'to mais@ said feeding und said hnlilingg nim-int; :may from said work-plate to permit work to be passed between them and into the 51mm, inclosud between Said arm and said work-plate.
